 # De – Moivre’s Theorem

A simple formula for calculating power of complex numbers in the form of cosθ and sinθ is known as de-moivre’s theorem. The De-moivre’s theorem. If n is integer (cosθ + isinθ)n = (cosnθ + isinnθ) Cube Roots of Unity: Let us the cube roots of z is 1 Z = 3√ (1) Z³ = 1 Z³ Read more about De – Moivre’s Theorem[…] # Domain, Co – Domain and Range

Let f be a relation from A into B then {x ϵ A: (x, y) ϵ R} is codomain of f and {y ϵ B: (x, y) ϵ f} is called range of f Domain: The domain is input values Range: The resultant value is called range Ex: if f = {(a, b), (c, d), Read more about Domain, Co – Domain and Range[…] # Kinematic Equations for Uniformly Accelerated Motion

Various representations are used to represented motion of any object like pictorial representation, graphs, and verbal representation etc. The branch of mechanics which studied the motion of an object is called kinematics. It describes the concept of motion with graphical representation of its basic term like displacement, velocity, speed, acceleration etc.  And motion equation which Read more about Kinematic Equations for Uniformly Accelerated Motion[…] # JEE ADVANCED exam to be held on 20th May, 2018

In spite of our best efforts we could not find a fixed point with respect to which we should study absolute rest and absolute motion. So, the study of relative rest and relative motion assumes importance. Consider two cars A and B running parallel to each other on same road with same velocities. No doubt Read more about Relative Velocity[…] # Locus

A locus is a set of points which satisfy certain geometric conditions. Many geometric shapes are most naturally and easily described as locus. For example, a circle is the set of points in a plane which are a fixed distance from a given point the center of the circle. Example: A locus The following diagrams give the locus of a Read more about Locus[…]
